Students' attitudes towards Digital Game-Based Learning (DGBL) in developing countries such as Indonesia are rarely investigated despite the fact that digital games are being used in secondary education increasingly. This research aims to explore students' attitudes towards DGBL in chemistry. We used a quantitative study method using a…

We present a modernization of the undergraduate physical chemistry laboratory experiment for determining the speed of sound in various gases from resonant frequencies in a spherical resonator. The resonator (schematic IR = 7.5 cm) is constructed by 3D printing with eco-friendly poly(lactic acid), a commercially viable alternative to traditional…

This paper describes a responsive, digital periodic table that has been specifically designed as a visual aid for high school or college chemistry classrooms and lecture halls. The periodic table runs in a web browser and can therefore be used in any classroom that has a digital projector and screen. It features click-to-highlight table cells that…

A hands-on activity appropriate for first-semester general chemistry students is presented that combines traditional VSEPR methods of predicting molecular geometries with introductory use of molecular modeling. Students analyze a series of previously calculated output files consisting of several molecules each in various geometries. Each structure…

A general systematic approach is proposed for the numerical calculation of multi-equilibrium problems. The approach involves several steps: (i) the establishment of balances involving the chemical species in solution (e.g., mass balances, charge balance, and stoichiometric balance for the reaction products), (ii) the selection of the unknowns (the…

The Northwestern University Initiative for Teaching Nanosciences (NUITNS) at nanohub.org Web site combines several tools for doing electronic structure calculations and analyzing and displaying the results into a coordinated package. In this article, we describe this package and show how it can be used as part of an upper-level quantum chemistry…

An understanding of the periodic table is central to the study of chemistry. So it is no surprise that it is included in the National Science Education Standards. But how can teachers get students excited about the periodic table? And how can teachers help them learn it in a way that challenges their critical-thinking skills? The authors'…

PhET Interactive Simulations (sims) are now being widely used in teaching physics and chemistry. Sims can be used in many different educational settings, including lecture, individual or small group inquiry activities, homework, and lab. Here we will highlight a few ways to use them in teaching, based on our research and experiences using them in…

Classifying a particle requires an understanding of the type of bonding that exists within and among the particles, which requires an understanding of atomic structure and electron configurations, which requires an understanding of the elements of periodic properties, and so on. Rather than getting tangled up in all of these concepts at the start…

The 20th century saw some of the most important technological and scientific discoveries in the history of humankind. The space shuttle, the internet, and other modern advances changed society forever, and yet many students cannot imagine what life was like before these technologies existed. In the project described here, students take a firsthand…

The National Science Education Standards suggest that students work as real scientists in the classroom (NRC 1996; 2000). To accomplish this task, the authors developed community-based inquiry lessons (CBILs) that provide students with the opportunity to solve problems as a class, based on the concept of whole-class inquiry (WCI) presented by…

The periodic table and the periodic system are central to chemistry and thus to many introductory chemistry courses. A number of existing activities use various data sets to model the development process for the periodic table. This paper describes an image arrangement computer program developed to mimic a paper-based card sorting periodic table…

A laboratory activity for an upper-level undergraduate course in instrumental analysis has been created around LabVIEW. Students learn rudimentary programming and interfacing skills during the construction of a fluorimeter assembled from common modular components. The fluorimeter consists of an inexpensive data acquisition module, LED light…

Medicinal chemistry is a specialized, scientific discipline. Computational chemistry and structure-based drug design constitute important themes in the education of medicinal chemists. This problem-based task is associated with structure-based drug design lectures. It requires students to use computational techniques to investigate conformational…

The application of technology in classroom settings has equipped educators with innovative tools and techniques for effective teaching practice. Integrating digital technologies at the elementary and secondary levels helps to enrich the students' learning experience and maximize competency in the areas of science, technology, engineering, and…
